United Nations Transitional Authority in Eastern Slavonia

February 1996 — January 1998

The UNTAES mission was established by UNSCR 1037 to oversee the peaceful re-integration of Eastern Slavonia, Baranja and Western Sirmium into Croatia after the Balkan wars.

Its mandate included ensuring the demilitarisation of the region and providing security to personnel from the International Criminal Tribunal for the former Yugoslavia (ICTY) who were carrying out exhumations at a mass grave site in Ovcara.

UNTAESs also conducted and observed successful elections in the region in April 1997.
